Spatiotemporal Dynamics and Controls of Vegetation Net Primary Production at Greater Bay Area Outer Ecological Barrier

Biological Diversity, Volume 2, Issue 4, Page 154-162, December 2025.
The spatiotemporal dynamics of NPP were evaluated for the ecological barrier of GBA, utilizing vegetation remote sensing, land use, and meteorological data. Results revealed that the vegetation NPP in the ecological barrier was 2.29 times that of the core area of GBA, highlighting its critical ecological function.

ICESat‐2 Pointing Calibration and Geolocation Performance

Earth and Space Science, 2021
ICESat‐2 science requirements are dependent on the accurate real‐time pointing control (i.e., geolocation control) and postprocessed geolocation knowledge of the laser altimeter surface returns. Prelaunch pointing alignment errors and postlaunch pointing

Mixing Patterns of River Deltas Obtained From Remotely Sensed Rouse Number

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract River deltas have complex vertical sediment dynamics within their distributary channel networks. These dynamics suggest that remotely sensed suspended sediment concentration (SSC), which captures surface conditions, is insufficient for investigating delta mixing.

A U.S. Scientific Community Vision for Sustained Earth Observations of Greenhouse Gases to Support Local to Global Action

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Managing carbon stocks in the land, ocean, and atmosphere under changing climate requires a globally‐integrated view of carbon cycle processes at local and regional scales. The growing Earth Observation (EO) record is the backbone of this multi‐scale system, providing local information with discrete coverage from surface measurements and ...

What's Next for Snow: Insights From the NASA Terrestrial Hydrology Program Community Snow Meeting

Earth's Future, Volume 13, Issue 12, December 2025.
Abstract Earth's snow cover strongly influences the climate system and represents an important resource for agricultural, industrial, and domestic water use. The last decade of snow‐focused research has improved our understanding of snow across scales. These efforts have culminated in new snow measurement instruments and methods, operational models for

Substantial Contribution of Woody Components to Rainfall Interception in Chinese Forests: Insights From a Refined Analytical Model

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Assessing rainfall interception (IR) is a critical yet uncertain aspect in hydrological cycle, particularly the quantification of relative contributions from leaves and woody components (e.g., branches, stems, and trunks) to IR. Nevertheless, the role of woody components in IR estimation remains largely unexplored and thereby has been ...
